A communications system may include a transmitting device for transmitting a modulated signal therefrom based upon first and second input data. The transmitting device may include a baseband injected pilot carrier (BPIC) generator for selectively generating BPIC data corresponding to the first input data, an interleaver for interleaving BPIC data with the second input data, and a modulator for modulating the interleaved BPIC data based upon a first modulation type and modulating the second input data based upon a second modulation type to provide a modulated signal. The communications system may further include a receiving device for receiving the modulated signal from the transmitting device. The receiving device may include a BPIC detector and a demodulator cooperating with the BPIC detector for demodulating the modulated signal from the transmitting device based upon the BPIC data to generate the first and second input data.
